1 PRIME Solutions for AMI systems Technology for energy efficiency

2 Telemanagement Most utility distribution companies have developed and implemented modernisation plans for their distribution lines, with the aim of improving energy efficiency. In some countries, these improvements are prompted by regulations that make it compulsory to provide a more intelligent network, covering such areas as power generation control, improvements to the distribution lines, remote metering and remote control of transformer substations or the installation of smart meters. A whole range of new possibilities has emerged in the area of smart metering that were completely unimaginable with traditional mechanical meters. The communications system offers benefits in PLC (Power Line Carrier) communication over the electrical network, at an optimised cost. Some of the most notable features of these meters with telemanagement are that they allow you remotely connect and disconnect power, obtain consumption load profiles, remotely read meters in real time and record network quality parameters. In addition to the smart meters that communicate over the electrical network, the main component of a system with this type of communication is the concentrator. This is a key component for the management of the entire network of meters, connected to a distribution transformer. The concentrator is responsible for communicating with both the meters and the central services that receive all of the data from each of the distribution company s concentrators. To ensure interoperability between the different actors and existing applications, it is preferable to use open and public standards, such as those established by PRIME Alliance. PoweRline Intelligent Metering Evolution PRIME promotes a public, open system with a non-proprietary telecommunications architecture, that will shape new AMM features and enable the construction of the new power grids of the future, i.e. the Smart Grids. PRIME is based on OFDM multiplexing on the CENELEC-A band. The ultimate goal of PRIME is to establish a full range of international standards that ensure interoperability between the equipment and systems of different manufacturers. 2

3 Telemanagement system Benefits of the system 1. Billing process The telemanagement system with PRIME PLC communications enables the meter reading process to be controlled automatically, thus eliminating reading errors and reducing the costs associated with managing meters. 2. Demand management From the information received from the meters, the concentrator allows you to create an accurate prediction of the energy demand in different time slots. This facilitates the management of the generation capacity of power distribution companies. 3. Technical management To facilitate the technical maintenance of installations, the system offers a number of features, including the efficient control of technical losses and fraud-related (non-technical) losses, the remote connection and disconnection of the end user s power supply, the option to perform a remote technical analysis of any user s electrical parameters - without the need for any physical intervention - and the remote configuration of each customer s contracted power. At the same time, it allows you to obtain power quality data at each measuring point. 4. Complex tariff system This latest generation of meters is capable of controlling flexible tariffs, which measure power consumption in different periods. This allows power distribution companies to design domestic contracts that will apply tariffs based on the actual cost of the energy, allowing each customer s tariff to be remotely adjusted according to the needs of the market.

4 Compact concentrator for telemanagement Concentrator COMPACT DC Serie Purpose of a PLC concentrator The main purpose of a PLC concentrator is to read the energy meters over the electrical network and export that data to one or more computer systems that are responsible for managing concentrators or, failing that, meters. The ability to send the same data collected by the concentrator to different systems results in faster billing, for example, as the measurements are obtained instantly. Not only power distribution companies and operators of distribution lines can optimise their procedures. Energy suppliers, energy service companies and even customers themselves can benefit from obtaining their consumption data, because the system allows them to know their consumption habits and optimise their tariff or contracted power. The new needs of the market, in terms of features and functionalities, have led CIRCUTOR to develop the third generation of PRIME concentrators, the COMPACT DC range. 4

5 Functionalities and features of COMPACT DC The COMPACT DC concentrator is normally installed in the transformer substation, by mounting it on a DIN rail and connecting it to the low voltage winding of the three-phase system. This allows the meters to be remotely managed through PLC communications, using the protocol standardised by PRIME Alliance. All of the information recorded by the meters is obtained using PLC. This information includes the load profiles, daily or monthly summaries of consumption and even quality parameters and any events that have occurred at the measuring point. As well as obtaining the readings, the concentrator allows you to manage the meter, either by changing the scheduled tariff or operating the circuit breaker to configure a new contracted power or disconnecting or reconnecting the power supply. Design COMPACT DC, the latest generation of PRIME PLC concentrators, offers a design with smaller dimensions, making it suitable for most cabinets on the market, and new features such as a built-in dual-sim 3G modem with 4 digital inputs. Another notable feature is that this is a compact solution in a single unit; telemanagement in distribution centres with two transformers, or for dual voltage transformers (COMPACT DC 2 dual concentrator). A 10 kv internal overvoltage protection device has been included in the Ethernet port of all COMPACT DC models, providing protection for 1 minute. In terms of the design of the enclosure, the COMPACT DC concentrator has a DIN rail attachment and a complete LED light indicator system on the front which provides quick and complete visual information about the overall operation of the concentrator. The electrical connection is at the bottom, using standard removable terminals, thus facilitating integration within the enclosure, both in terms of securing the unit and accessing the wiring and routing the wires to conduits, terminals or circuit breakers. LV Supervision system The implementation of a telemanagement system allows you to find out information at the supply end and to interact with the measuring device. In this context of remote measurement and management of the grid, we must not forget the transformer substation itself, which does not normally have measurement systems that offer visibility regarding the transit of energy through the distribution transformer, the highest point of LV distribution lines. COMPACT DC concentrators have built-in units that monitor all of the distribution lines, this is called the LV Supervision System. This measurement module is a three-phase meter, which measures forward voltage and current through current transformers. This monitoring functionality provides a large amount of information to the company that operates the grid, as well as controlling and monitoring the LV network. Some of the most notable features of the LV Supervision System are: Energy balances (obtaining technical and non-technical loss rates) Control of the load level of each transformer phase. Preventive monitoring of the network. This allows any problems in the network to be detected before they affect and are reported by customers. MV parameters calculated. 5

6 COMPACT DC Series Compact DC Ethernet PLC coms PLC Communications In terms of PLC communications, the concentrator has a passive three-phase injection system, that injects the maximum power permitted by standard EN 50065, by all 3 phases at once. In addition to the three-phase injection, the concentrator can be configured, via the web, to inject through one of the 3 phases. This is used in cases where one of the phases interferes with the communications of the other phases. Models The PRIME COMPACT DC range of concentrators is available in different models, depending on the needs of each installation. The most basic model is the COMPACT DC SBT which, as well as featuring the PLC concentrator, includes the LV supervision system. In addition to the supervision system, the COMPACT DC 3G concentrator comes with a built-in 3G modem. If the concentrator needs to monitor any signals or external indicators, such as floor or fire detectors, door open sensors or MV isolator status sensors, the most suitable model is the COMPACT DC 4I concentrator, which, in addition to the LV supervision system, comes with a module that has four 10 kv digital inputs with 1-minute insulation. In transformer substations where there is no need to monitor the network with a LV supervision system and a small-sized unit is required, the COMPACT DC BASIC model is the most suitable concentrator, which as well as offering concentrator functionality, includes a 3G modem. The most complete concentrator model is the COMPACT DC 2. This concentrator is the unit for transformer substations with two transformers, as it offers two fully insulated PLC injection systems, two LV supervision systems to monitor each threephase network and a module with 4 digital inputs. Applications Like its previous versions, the COMPACT DC is used to provide communication with energy meters with PRIME technology, designed for measuring in LV networks and exporting the information obtained by PLC to the utility company s higher reading and billing systems. The COMPACT DC is normally installed on the transformer substation, whether indoors or outdoors, connected to the three-phase system s LV winding. Whoever operates the network, normally the power distribution company, will manage the entire network of concentrators and, at the same time, through these, all of the meters connected to each of the LV networks. Communication with the meters and concentrators is two-way, because the concentrator or network operator sends requests to the meters and the meters send automatic records to the concentrator and the central services. 6

8 Energy meters for residential applications residential meters B200RCP / B410RCP Type 5 meters Residential meters make up the bulk of the systems that have to be controlled by power distribution companies. The PRIME system provides a more effective solution for the telemanagement of this kind of meter. 8

9 Applications CIRCUTOR has developed both the single-phase and three-phase meter with PRIME communications, for residential power supplies below 15 kw. The main features of these types of systems are as follows: Measurement of active and reactive energy, with the ability to distinguish between energy consumed and generated (4 quadrants). It remotely collects information about energy consumption, eliminating the errors associated with manual readings and eradicating the need to make estimates. Inclusion of a circuit breaker with two main functions. Thanks to the first function, the utility company can remotely disconnect and reconnect the power supply of any customer. The second is used for power limitation, allowing the contracted power to be configured in each meter. When the power consumed exceeds this value, the meter itself will disconnect the electric supply. To restore it, it will be necessary to perform a safety operation, which consists of opening the main switch, at which point the meter instantly detects that the circuit is open and restores the supply. The unit has an internal memory that allows a load curve to be logged, storing up to three months, at an hourly rate. This information allows the utility company to know the consumption habits and adapt its generation capacity to the actual demand.

10 Energy meters for industrial applications and SMEs industrial meters B410DP / B410TP Type 3 and 4 meters This PRIME telemanagement system provided by CIRCUTOR not only offers a robust solution for residential meter management, it also enables the integration of industrial direct and indirect measurement meters for low voltage supplies above 15 kw. 10

11 Applications Although telemanagement systems were originally created to deliver effective reading and management of residential meters, it is to be expected that during the second phase, or even in the initial project, one of the objectives set was to take advantage of all of the resources that had already been deployed to integrate the industrial meters connected to the same low voltage network. CIRCUTOR has integrated PRIME communications into the direct and indirect measurement three-phase energy meters. By including these customers, complete telemanagement of all supplies connected to a transformer substation is provided. This way a more complete energy balance is achieved, because you not only have readings from residential meters, but also from industrial meters, meaning that more accurate information about technical and non-technical losses can be obtained.

SoftWatt SoftWatt PRIME software is an application designed for utilities and power distribution companies that allows all of the tariffing, measuring and communications parameters of the meters to be configured with the PRIME protocol. SoftWatt PRIME is compatible with all PRIME units, whether single-phase or three-phase. Among other features, the application includes: Configuration of contracts, public holidays and contracted power Configuration of the circuit breaker and the display view. Downloading of load curves, events and energy closes. Configuration of transformation ratios in indirect units. Power quality parameters. 12

13 Overvoltage protection The PSM-PLC family of overvoltage protection devices includes a complete range of compact type-2 transient overvoltage protection devices with replaceable cartridges. It is especially designed to provide full and effective protection against transient overvoltages in the electrical network and particularly for networks with PLC communication. Adequate protection is achieved through staging; adapting the levels of protection to the part of the device where they are installed and to the systems inside it. These protection devices have a built-in dynamic isolator, to isolate the protection element from the network when it ceases to be effective. The PSM-PLC range is composed of class II protection devices, with various discharge capacities: 20 ka and 40 ka, with an 8/20 µs curve. This protection device can be installed in the telemanagement cabinets, where the concentrators and wireless communication components will be located, to protect both their power supply and the concentrator's three-phase coupling. Models Code Type Description P PSM20/400 2-pole overvoltage protection device. P PSM40/400 4-pole overvoltage protection device. 3G / GPRS modem router SGE-3G is the CIRCUTOR modem router. It is designed to communicate with PRIME concentrators and meters via the Ethernet ports, RS-232 and RS-485. The modem's main feature is that it is able to communicate with EDGE / HSDPA (High Speed Downlink Packet Access), as well as enabling the connection to be configured with either a static or dynamic IP (through DynDNS services). All SGE-3G modem configuration is performed on its web site. Code Type Description Q30230 SGE-3G/GPRS modem router GPRS-3G modem router with Ethernet communication Current transformers CIRCUTOR provides a number of versions in its range of low voltage current transformers, depending on the requirements of the power distribution company. The standard transformers used for official measurements are the TRMC 210 and TRMC 400, 10 VA and 0.5S (or 0.5) class. CIRCUTOR has also developed the same range of transformers but with less power (2.5 V A), guaranteeing the same accuracy but at a far more competitive price. LOC optical reader CIRCUTOR has an optical head which is an essential accessory for the local reading or configuration of PRIME meters. CIRCUTOR has two different models, depending on the type of communication interface, whether RS-232 or USB. CIRCUTOR also offers an alternative solution to the transformers currently available, the new, more compact TRMC-X3 range (2.5 VA and 0.5S class), with indoor and outdoor installation models, in which the three current measurement transformers are arranged on a single mechanical support at a more cost-effective price, offering easy assembly and optimising performance. All while maintaining the accurate measurements which are characteristic of these devices. * See models in specific catalogue.

19 CIRCUTOR has developed a complete range of devices based on the PRIME telemanagement system, offering compact solutions for the industrial, urban and rural environments. Much of our efforts have been devoted to designing concentrators as key components for the management of the system, offering the most suitable solution for each operating environment. The main key to the success of this system is its compact design, on a DIN rail, which makes it easy to install in any type of enclosure. Although current legislation only covers the inclusion of supply points of under 15 kw in telemanagement systems, CIRCUTOR has already opted to propose broader solutions, making it possible for indirect measurement meters for industrial installations to be included in the system.
